Collagen in food

It's collagen the most abundant protein in the body which does not exist only in food. It is also found in bones, blood vessels, tendons, muscles, skin and the digestive system. This protein along with keratin replaces dead skin cells and keeps it firm.

Collagen as a medicine

Collagen is the most abundant protein in the human body and the major protein component of connective tissue, bone and skin. They can occur in the form of ligaments, mesh, fibrils and insoluble fibers. The characteristic amino acids for collagen are hydroxylysin, hydroxyproline, proline and glycine.

There are 19 types of protein four of which are the most important. They are numbered in Roman numerals and each has a unique role to play. Thus, type IV collagen is found in membranes, type III collagen in embryonic tissues, type II collagen in cartilage, and type I in bone.


Over the years, the production of protein in the body begins to weaken, and due to the lack of collagen, the first signs of aging appear, such as joint pain, wrinkles and sagging skin.

On slow production affected by excessive sun exposure, a diet high in sugars and smoking, and protein-related illnesses most commonly occur due to digestive problems that affect collagen production, a combination of genetic damage and poor intake of protein-containing foods.

It is required for the health of teeth, nails and hair, for leaky gut syndrome, for the cardiovascular system, for vitality and muscle, for bone and joint health, skin, for liver health and for metabolism.


It can also be supplemented naturally by stimulating the production of collagen externally and internally. Some ways to stimulate collagen production work and some do not. Collagen creams are the ones that don't work because the molecules in them are too big to penetrate the skin.

Collagen in food

Proper nutrition and physical activity can mitigate collagen loss, which is why it's good to know what foods you can find in it.

There are several natural ways that are effective in increasing protein in the body, and one of them is nutrition. Foods that are protein sources are mostly foods that can be linked to collagen levels such as chicken, seafood, beef, fish and eggs.


Coming up protein rich foods:

  • dark green vegetables
  • red fruits and vegetables
  • omega fatty acids
  • Turkey meat
  • avocado oil
  • soy products
  • legumes
  • blueberries and prunes
  • food rich in sulfur
  • chocolate
  • white tea

Many factors encourage and support the production of collagen in the body, some of which include manganese, copper, food yellow, vitamin C, proline and foods rich in anthocyanins. Therefore, their intake into the body should be given special attention.

One needs to be aware that certain foods stimulate collagen growth more than other foods, and animal products such as Poultry, milk, eggs and fish help in protein production, but that is why vegetarians should not worry. It can also be used in recipes for fruit treats or homemade jellies.
